California’s new net metering rules (NEM 3.0) have made going solar less attractive for many homeowners. Under NEM 3.0, solar customers only receive pennies per kWh for excess power they feed back to the grid. So homeowners who install solar to offset EV charging costs will save less than those under previous terms.
Existing solar customers face a dilemma.
According to the new rules, an existing solar customer under NEM 1.0 or NEM 2.0 can only add up to 10% of the original system size. Otherwise, they will lose their current terms and be placed under NEM 3.0. The average existing solar system can require an additional 8-10 solar panels for EV charging*, which usually exceeds the 10% limit.
One solution for homeowners who want to install solar to charge their EVs is to add as many solar panels as they need to their homes but not connect them to the grid.
Consumers could use this solar power to charge their EVs and not sell it back to the utility company at a reduced price. However, this would require homeowners to charge their EVs when the solar panels produce power during the day.
Solar charging during the day will save people a lot of money.
Currently, PG&E customers pay about 38 cents per kWh. With an EV solar charging station at home or work, the cost would be less than 10 cents per kWh (averaged over the 25-year warranty period of the solar panels).
Another solution is for employers to install solar panels on their properties and offer free EV charging to their employees.
This would allow employees to charge their EVs while the panels produce energy during their workday. And it’s a nice perk to offer employees!
Solar EV charging is a win-win for consumers and utilities.
It can help consumers save money on their energy bills and help utilities reduce the strain on the grid.
